[PATCH 0/2] virtio_net: add page_pool support

[Vishwanath Seshagiri <vishs@meta.com>]

Introduce page_pool support in virtio_net driver in order to recycle
pages in RX buffer allocation and avoid reallocating through the page
allocator. This applies to mergeable and small buffer modes.

The patch has been tested using the included selftests and additional
edge case scripts covering device unbind/bind cycles, rapid interface
open/close, traffic during close, ethtool stress with feature toggling,
close with pending refill work, and data integrity verification.
